Dropper Assemblies are composed of three main parts:
Bulb: We only use the leak-resistant patented DripTrap dropper bulbs in our assemblies. The bulb is made of premium lab quality silicone and is designed to allow for a full 1ml draw with each squeeze. Color: Black
Cap: The caps are polypropylene ribbed standard caps with a 20-400 finish. These caps will fit bottles with an 18-400 neck size and are typically paired with our 1oz (30mL) Boston Round style bottles. Color: Black
Pipette: These pipettes are made of plastic (polypropylene), have a 76mm length (best for 1oz/30mL bottles), and are graduated. The graduation marks on these pipettes are printed. When the graduation marks are printed on it allows for a clean black ink mark but those marks can dissolve away in more abrasive liquids. Unless you know that these will work for you, we almost always recommend our chemically stained graduated pipettes or our pipettes with molded graduation marks. Chemically stained graduated pipettes are the industry standard and are featured on almost every dropper assembly we offer, while the molded pipettes are available in specific styles and sizes. Graduated: Yes
